Do FLECHETTES work like in Video Games/Hollywood Movies?

In this video we test out flechettes (little arrows in French), something that always sent shivers up my spine. Do they REALLY work like they do in popular culture or are they a novelty? You will notice I did not even mention the name of the company that made these. Thank you Anthony, a viewer who wanted to see how these actually worked. Also, thank you channel members and Patreon Supporters! https://www.patreon.com/user?u=3751733 There are no firearms in this video, YT.
